Benefits of technology

[0012]Still another aspect of the invention is a method of preventing sympathetic detonation of munitions comprising at least partially enclosing each munition in a generally cylindrical HDPE sleeve.

Problems solved by technology

SD yields substantial collateral damage including the loss of life and critical military equipment.
The problem of propagation of the detonation reaction has existed since initial fielding of munitions containing high explosives.
There had been no practical method to prevent SD in packaged high explosive ammunition until the development in the 1960s of anti-fratricide stowage in ammunition compartments for combat vehicles, specifically, the M1 Abrams tank.
Known methods of mitigating or eliminating SD address the problem in stowed configurations onboard combat vehicles, but are not practical for the logistical life-cycle of munitions.
SD during transport involves large quantities of munitions, and can potentially have catastrophic consequences resulting in massive casualties, damage to military and civilian equipment and damage to surrounding infrastructure.
A malfunction in a vehicle's heater resulted in a high number of casualties, with loss of life and military equipment (ammunition, vehicles, etc) as well as damage to the land and surrounding infrastructure.

Embodiment Construction

[0023]The invention mitigates or eliminates the problem of sympathetic detonation (SD) in large caliber high explosive packaged artillery ammunition. The invention may be applied to other types of ammunition as well (such as missiles, mines, mortars, grenades, etc). The invention includes a generally cylindrical sleeve that is placed over high-energy munitions. The sleeve is preferably made of high-density polyethylene (HDPE). The sleeve is of a thickness sufficient to prevent neighboring high-energy munitions from SD. Thus, a high order explosive event in one ammunition round will not propagate to neighboring ammunition rounds. The invention will also mitigate and / or prevent the loss of life and subsequent collateral damage.

[0024]FIG. 1 is a side view of a munition 10. The munition 10 shown is an artillery projectile, but the invention is applicable to other types of munitions, also. Munition 10 includes a rear end 11, a front end 13, a lifting plug 12 at the front end 13, a fuze w...

Abstract

A sympathetic detonation barrier for a munition includes a generally cylindrical polyethylene sleeve disposed over the munition. Preferably, the sleeve comprises HDPE. The sleeve may include vent openings in a side wall. In one embodiment, the sleeve extends from substantially a rear end of the munition to substantially a rear end of a fuze well of the munition.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 USC 119(e) of U.S. provisional patent application No. 60 / 807,833 filed on Jul. 20, 2006, which application is hereby incorporated by reference.STATEMENT OF GOVERNMENT INTEREST[0002]The inventions described herein may be manufactured, used and licensed by or for the U.S. Government for U.S. Government purposes.BACKGROUND OF THE INVENTION[0003]The invention relates in general to munitions and in particular to packaging for artillery ammunition that mitigates or eliminates sympathetic detonation.[0004]Sympathetic detonation (SD) is the propagation of the detonation from one round of ammunition to adjacent rounds of ammunition when collocated in stowage or shipping configurations. SD yields substantial collateral damage including the loss of life and critical military equipment. The problem of propagation of the detonation reaction has existed since initial fielding of munitions containing high exp...
